Ocular ultrasound, B-scan ultrasonography, or an ophthalmic echograph, uses sound waves to take pictures of the structures of the eye and surrounding orbit. This scan takes a two-dimensional cross-sectional image of the eye. It can help accurately view and measure structures such as the lens, choroid, sclera, vitreous, and retina. It is helpful when there is difficulty examining the eye normally, like in the case of severe cataracts or vitreous hemorrhage. These are real time images that can give your doctor a live view of eye structures unable to be seen by microscope alone. It is a useful tool when diagnosing certain eye conditions such as retinal detachment, dislocated lens, choroidal nevus, and ocular melanoma.
An Ocular ultrasound is very similar to an ultrasound that a doctor would take of your belly. A probe is used on the outside of a closed eyelid and gently vibrates with the help of lubricating jelly. Ultrasounds are safe, do not expose you to radiation, are low cost, and can easily and quickly be done in the office during your visit. Our ultrasound is portable enough to be housed on a cart, meaning you don’t even have to leave your exam chair to undergo the test. Our physician or ultrasonographer can take a picture of the entire globe of the eyeball in just six quick movements.
The occasional patient in other general eye practice who is perceived to need imaging may be referred to a hospital for CT or MRI scans. These are timely and costly, and may be unnecessary. In many cases, a careful history, examination by the doctor combined with an ultrasound scan can correctly diagnose the problem without the need for far more expensive tests.
Ultrasonography has established itself as one of the most important diagnostic tools in ophthalmology. The value of the images are highly dependent on the skill, technique, experience, interpretation, and dedication of the ultrasonographer.
